점점 증가하는 모바일 데이터 트래픽에 대처하기 위해 최근 우리는 셀룰러 초고밀도 무선 접속 네트워크(RAN) 개념을 제안했습니다. 셀룰러 초밀도 RAN에서는 기지국(BS) 커버리지 영역(셀)에 다수의 분산 안테나를 배치하고 사용자 클러스터를 구성하여 소규모 분산 다중 사용자 다중 입력 다중 출력(MU-MIMO)을 수행합니다. ) 동일한 주파수 자원을 사용하여 각 사용자 클러스터에서 병렬로 전송 및 수신합니다. 또한 셀룰러 초고밀도 RAN에서 발생하는 셀 내 간섭과 셀 간 간섭을 모두 효과적으로 완화하기 위한 분산형 간섭 조정(IC) 프레임워크를 제안했습니다. 본 프레임워크에서 채택한 셀 간 IC는 CS(Channel Segregation) 알고리즘을 적용하여 구현한 FFR(Fractional Frequency Reuse)이며 본 논문에서는 CS-FFR이라고 합니다. CS-FFR은 사용 가능한 대역폭을 여러 하위 대역으로 나누고 여러 하위 대역을 서로 다른 셀에 할당합니다. 본 논문에서는 CS-FFR의 최적화에 중점을 두고 컴퓨터 시뮬레이션을 통해 링크 용량을 최대화하기 위한 최적의 대역폭 분할 수와 하위 대역 할당 비율을 찾습니다. 또한 셀룰러 초고밀도 RAN에서 CS-FFR의 수렴 속도에 대해서도 논의합니다.

Abstract: To cope with ever growing mobile data traffic, we recently proposed a concept of cellular ultra-dense radio access network (RAN). In the cellular ultra-dense RAN, a number of distributed antennas are deployed in the base station (BS) coverage area (cell) and user-clusters are formed to perform small-scale distributed multiuser multi-input multi-output (MU-MIMO) transmission and reception in each user-cluster in parallel using the same frequency resource. We also proposed a decentralized interference coordination (IC) framework to effectively mitigate both intra-cell and inter-cell interferences caused in the cellular ultra-dense RAN. The inter-cell IC adopted in this framework is the fractional frequency reuse (FFR), realized by applying the channel segregation (CS) algorithm, and is called CS-FFR in this paper. CS-FFR divides the available bandwidth into several sub-bands and allocates multiple sub-bands to different cells. In this paper, focusing on the optimization of the CS-FFR, we find by computer simulation the optimum bandwidth division number and the sub-band allocation ratio to maximize the link capacity. We also discuss the convergence speed of CS-FFR in a cellular ultra-dense RAN.
